Multiplication of tumor cells is suppressed by the same set of genes as those that suppress multiplication of normal cells of the same type during differentiation; tumors arise when these genes are impaired.

Oncogenic mutations (and oncogenic viruses) release the brakes that tumor-suppressor genes apply.

-essentially says that the laws of physics don’t change when we switch between different reference frames.

For the past century there have been two incompatible theories on how the universe works:

Gravity (courtesy of Einstein’s general theory of relativity) and
Quantum Theory (used for the other three fundamental forces of nature: electromagnetism and the strong and weak nuclear forces ).

Both work ok, except in extreme environments (like inside a black hole). So, scientists are looking for a good theory of Quantum Gravity. The problem is that relativity wants gravity to be continuous, while quantum theory wants it grainy.
